OF THE FIRTH OF FORTH. 7d 
chiefly single valves, but sometimes a 
perfect specimen (JZ). 
We have collected this species at Aber- 
dour, ete. 
CARDITIDA. 
Cyamium minutum (Fabr.). 
Living among small seaweeds in rock 
pools, ete., at North Berwick and Dun- 
bar. Very common at the Isle of May. 
A clear white form is rare at North

CARDIIDA. 
Cardium echinatum (Linn.). 
Firth of Forth (B.,and Ed. Mus.) ; Bass 
Rock, 24 fathoms, and St Abb’s Head 
40 fathoms (Metz. and Mey.). 
Taken alive between Granton and Cramond 
Island. Specimens with the prickles worn 
smooth are not uncommon, and bear a 
great resemblance to C. tuberculatum, and 
have been mistaken for it. Good prickly 
specimens are frequent in Newhaven Har- 
bour, brought in by the fishermen. Single 
valves occur along the whole coast (JZ). 
This species is not uncommon in the Firth. 
We have dredged it off Longniddry, in 7 
fathoms; west of Inchkeith, in 12 fathoms; 
and have collected it on the beach at 
Largo and Portobello. 
C. fasciatum (Mont.). 
C. edule (Linn.). 
We have a specimen of this species from 
Elie. 
Firth of Forth (MB., and Ed. Mus.).

it at Cramond, Newhaven, Elie, North 
Berwick, Aberdour, etc.
